Application filed January 26, 1917. Serial No. 144,595. r

' To all 107mm it may concern:

Be it known that I, VVINTER W. MYERS, a citizen of the United States, residing at Brooklyn, in the of New York, have invented certain new and useful Improvements in Balanced Win- I following is a full, clear, and exactdescription.

The invention which constitutes :the subjectmatter of this application relates to improvements upon what is commonly .known as the Austral window.

Referring to the drawings: l igure 1 is a vertical section through the casing and sashes of a balanced window taken at .right angles to the plane of the window.

Fig. 2 is plane of the window.

Fig. 3 is a detail section of a portion of the window illustrating the mode of attachment of-the detachable portion of the parting strip.

F 1 is a section, similar to Fig. 1, illustrating the position of the parts when the sashes are in openposition.

Fig. 5 is a'section taken on line 55 of Fig. 2.

Fig. 6 is a sectiontaken on line 66 of Fig. 2.

Fig. 7 is an enlarged view of the sash guiding means.

Fig. 8 is a spring meta-l backing for the member supporting the lower guide roller.

Referring to the drawing in detail, the reference characters .10, 11 and 12 designate the upper, side and lower portions of a hol low metal ja-mb for a window which is of the Austral type, and in which are mounted the upper sash 13 and the lower sash 14 balanced on the arms 15 (only one being shown), as will be understood.

The vertical side portions of the jamb are provided on the interior thereof with grooves 16, preferably of rectangular shape, which are adapted to receive correspondingly shaped parting strips 17 and 18 riveted to the hollow jamb or otherwise secured in said groove. The parting strip 17 for the side jamb is provided with a weather strip 19 projecting outwardly from and at right angles to the plane of the window. and the upper sash 13 is provided with a groove 20 to receive the weather strip 19,

a vertical section taken in the .the upper 1 portion of county of :Kings and State flange or weather strip face ofthe said sash.

the groove being enlarged so that the sash may be readily assembled when it has been reversed for cleaningor other purposes. The lower parting strip .18 is provided with a corresponding 21 adapted toenter into a corresponding groove v22, but this groove is not. enlarged, to be so, sincezthe method of removing or reversing this sash is somewhat different from the reversing, assembling or removal of the upper sash, as will appear later on.

As will be apparent from Figs. 5 and 6, the jambs are preferably offset, as indicated at 23, andthis serves to prevent either of the sashes from falling outwardly, thereby avoiding injury to the pedestrians below. This is particularly true with respect to the upper sash, which is reversed for cleaning or adapted to be entirely removed by taking out the removable strip portion 24 of the parting strip, as will be understood. The portion 24: of the parting strip is'held in place byits upper end engaging under a flange 25 of the main parting strip and by means of the slide 26 entering a socket 27 in thepivot block 28.

The upper sash is provided with aeguide roller 29, which is preferably mounted on an angle-iron 30 (see Fig. 6) secured'to the This .guide' roller has a loose fit in the partingstrip in which it is adapted'to move upwardly and downwardly. The upperjamb'is provided withza'boss 31, extending across the top, which serves as a' parting strip at this end. Extending across the top of the jamb is a bead 32 provided with a cam surface which engages with the outer and upper edge 33 of the upper sash in such fashion that during the final closing movement the latter is cammed inwardly so as to enable it to make a weather-tight engagement with the various parting strips.

The guide roller 34 for the lower sash is fixed to a member 35 (see Figs. 5, 7 and 8 slidably mounted upon the base plate 41 of the said sash. When it is desired to reverse or remove the lower sash the guide roller is merely withdrawn from the groove of the parting strip 18. The member is held in fixed position by suitable means, such as rivets 36. To slide the member 35 it is only necessary to direct a pull upon the finger sashes or to the r piece 39 to move it beyond the end of spring plate 40. This spring plate is fixed upon the base plate a1.

' The base 12 of the window jamb is provided with an upwardly projecting boss 37, the lower edge of the sash being correspondingly recessed to fit over this boss. On the base there is provided a cam surface 38 which serves to force the lower sash, during its closing movement, in weathertight engagement with the parting strips.

V'Vhat I claim is l. In a window of the class described, the combination of upper and lowersashes, with a frame therefor provided with grooved parting strips against which each of said sashes normally engages, balancing levers connected at their ends to the upper and lower sashes, and guide means on said sashes for engaging the grooves in the parting strips to guide the sashes and permit them to wing on their pivots and assume angular positions with respect to the frame.

2. In a window of the kind described, the combination with upper and lower sashes, of a frame therefor provided with parting members, balancing levers pivoted to the frame and having their ends pivotally connected to I the upper and lower sashes respectively, weather stripping provided between said parting members and one or both of said sashes, and guides attached to said sashes for slidably engaging said parting members to guide the sashes and permit them to swing on their pivots and assume angular positions with respect to the frame.

3. In a window of the class described, the combination with upper and lower sashes, of a frame therefor provided with a parting strip against which said sashes normally engage, balancing levers connected at their ends to the upper and lower sashes, guide means for said sashes slidably engaging said parting strip, and cooperating means on said sashes and parting strip for effecting a weather-tight engagement between the same.

4. In a window of the class described, the

engaging said grooved parting strip,

combination with upper and lower sashes, of a frame therefor provided with a grooved parting strip against which said sashes normally engage, balancing levers connected at their ends to the upper and lower sashes, guide means for said sashes an a flange and groove connection between the sashes and parting strip for effecting a weather-tight engagement between the same.

5. In a window of the class described, the combination with upper and lower sashes, of a frame therefor provided with grooved parting strips against which each of said sashes normally engages, balancing levers connected at their ends to the upper and lower sashes, guide means on each of said sashes for slidably engaging said parting strips, one of which is adapted to be moved laterally of its sash and out of the corresponding path of the grooved parting strip and a flange and groove connection between the sashes and'parting strip for effecting a weather-tight engagement between the same.

6. In a window of the class described, the combination with upper and lower sashes, of a frame therefor provided with grooved parting strips, a section of which is adapted to be removed to permit the release from the said grooves of the slidably engaging means upon one of the sashes, each of said sashes normally engaging said parting strips, balancing levers connected at their ends to the upper and lower sashes, guide means on each of said sashes for slidably engaging said parting strips, one of which is adapted to be moved laterally of its sash and out of the path of the corresponding grooved parting strip, and a flange and groove connection between the sashes and parting strips for effecting a weather-tight engagement between the same.

In testimony whereof I affix my signature.
